1491–1547, king of England (1509–47); second son of Henry VII. The declaration that his marriage to Catherine of Aragon was invalid and his marriage to Anne Boleyn (1533) precipitated the Act of Supremacy, making Henry supreme head of the Church in England. Anne Boleyn was executed (1536) and Henry subsequently married Jane Seymour, Anne of Cleves, Catherine Howard, and Catherine Parr. His reign is also noted for the fame of his succession of advisers, Cardinal Wolsey, Sir Thomas More, and Thomas Cromwell
